Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have
we have
The leading coefficient is negative, that means the parabola open downward
The zeros of the function are
Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
